DESCRIPTION OF THE EMBODIMENTS

A clear and complete description will be made to the technical solutions in the embodiments of the present invention below. Apparently, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

Referring to FIGS. 1-8, the present invention provides a human-machine interaction sport vehicle 10. The human-machine interaction sport vehicle 10 includes a vehicle body, a rotating structure 2, two wheels, a hub motor, and a balance control system. The vehicle body includes a mounting plate, a top cover and a bottom cover, and the mounting plate is disposed between the top cover and the bottom cover and matched with the two. The mounting plate includes a first mounting plate 1 a and a second mounting plate 1 b which are symmetrically arranged and rotatable relative to each other. The first mounting plate 1 a is rotatably connected with the second mounting plate 1 b. The rotating structure 2 is configured to connect the first mounting plate 1 a and the second mounting plate 1 b, and enables the first mounting plate 1 a and the second mounting plate 1 b to rotate relative to each other. That is, the first mounting plate 1 a is rotatably connected with the second mounting plate 1 b through the rotating structure 2. The two wheels are disposed on two sides of the mounting plate and can rotate about the mounting plate. The hub motor is used for outputting power so as to drive the two wheels to rotate. The balance control system is connected with the hub motor for controlling the hub motor to drive the two wheels to rotate.

Referring to FIGS. 1, 2, 5 and 6, the first mounting plate 1 a includes a top surface 1 a 1 and a bottom surface 1 a 2 which are opposite to each other. The second mounting plate 1 b includes a top surface (not shown) and a bottom surface (not shown) which are opposite to each other. A first groove 1 a 3 and a second groove (not shown) are respectively formed in the bottom surface 1 a 2 of the first mounting plate 1 a and the bottom surface of the second mounting plate 1 b. The rotating structure 2 includes a rotating rod 2 a. The rotating rod 2 a is accommodated in the first groove 1 a 3 and the second groove. In order to ensure that the first mounting plate 1 a and the second mounting plate 1 b can rotate relatively, the rotating rod 2 a is rotatably matched with at least one of the first groove 1 a 3 and the second groove.

In the present embodiment, the rotating rod 2 a is rotatably matched with the second groove, and the rotating rod 2 a is fixedly matched with the first groove 1 a 3 (they cannot rotate relatively). Further, in the present embodiment, the cross sections of both the first groove 1 a 3 and the second groove are semicircular, and the rotating rod 2 a is a cylindrical drive rod. It can be understood that after the rotating rod 2 a is accommodated in the first groove 1 a 3 and the second groove, the rotating rod 2 a can rotate relative to the first groove 1 a 3 and the second groove. In order to ensure that the rotating rod 2 a is rotatably matched with the second groove, the rotating rod 2 a is fixedly matched with the first groove 1 a 3, and components capable of limiting the rotating rod 2 a to rotate relative to the first groove 1 a 3 are provided on the rotating rod 2 a and the first groove 1 a 3.

Specifically, referring to FIG. 6 and FIG. 7, the rotating rod 2 a includes a first end (not shown) and a second end (not shown) which are opposite to each other. The first end of the rotating rod 2 a can be defined as one end being close to the first mounting plate 1 a. It can be understood that the first end of the rotating rod 2 a can also be defined as one end being away from the first mounting plate 1 a. In the present embodiment, the first end of the rotating rod 2 a is defined as the end being close to the first mounting plate 1 a. The rotating structure 2 further includes a first pressing block 2 c and a second pressing block 2 d. The first pressing block 2 c and the second pressing block 2 d are fixedly mounted on the first mounting plate 1 a and the second mounting plate 1 b, respectively. The first end of the rotating rod 2 a is disposed between the first pressing block 2 c and the first mounting plate 1 a, and is engaged with the first pressing block 2 c. The second end of the rotating rod 2 a is disposed between the second pressing block 2 d and the second mounting plate 1 b, and is rotatably connected with the second pressing block 2 d and the second mounting plate 1 b in a matching manner. Of course, in other embodiments, one end of the rotating rod 2 a is square and the other end is circular; correspondingly, the cross section of the first groove 1 a 3 is square, and the cross section of the second groove is semicircular. In this way, when the rotating rod 2 a is mounted in the first groove and the second groove, the squares are matched with each other, and the circles are matched with each other, thus ensuring that the rotating rod 2 a is rotatably matched with the second groove, and the rotating rod 2 a is fixedly matched with the first groove 1 a 3 (they cannot rotate relatively).

Further, referring to FIG. 7, the first end of the rotating rod 2 a is configured with a first engaging portion 2 a 1. Referring to FIG. 8, the first pressing block 2 c is configured with a second engaging portion 2 c 1 thereon. The second engaging portion 2 c 1 of the first pressing block 2 c is engaged with the first engaging portion 2 a 1 of the rotating rod 2 a. When the first pressing block 2 c is fixed to the first mounting plate 1 a by a fixing member 2 e (e.g., a screw), the second engaging portion 2 c 1 of the first pressing block 2 c is engaged with the first engaging portion 2 a 1 at the first end of the rotating rod 2 a to fix the first end of the rotating rod 2 a in the first groove 1 a 3, so that the first end of the rotating rod 2 a is fixedly matched with the first groove 1 a 3 without relative rotation. Specifically, the second engaging portion 2 c 1 is a square groove formed in the first pressing block 2 c toward the mounting plate 1 a, and the first engaging portion 2 c 1 is a square surface formed on the circumferential surface of the first end of the rotating rod 2 a, that is, a square block is formed on the first end of the rotating rod 2 a. After the square block on the first end of the rotating rod 2 a is located in the square groove of the first pressing block 2 c, the first end of the rotating rod 2 a is engaged with the first pressing block 2 c by the matching between the square groove and the square block.

Referring to FIG. 7 and FIG. 8, the second end of the rotating rod 2 a is configured with a first limiting portion 2 a 2. The second pressing block 2 d is configured with a second limiting portion 2 a 1 thereon. The second limiting portion 2 a 1 is matched with the first limiting portion 2 a 2 to limit the rotation angle of the rotating rod 2 a.

Specifically, the first limiting portion 2 a 2 is an arc slot. The second limiting portion 2 d 1 is a limiting block, and a dimension H of the second limiting portion 2 d 1 in a direction perpendicular to the bottom surface of the second mounting plate 1 b is smaller than a depth L of the first limiting portion 2 a 2. A maximum rotation angle between the first mounting plate 1 a and the second mounting plate 1 b can be limited by the cooperation of the first limiting portion 2 a 2 and the second limiting portion 2 d 1. The meaning of limiting the maximum rotation angle between the first mounting plate 1 a and the second mounting plate 1 b is to enable the relative rotation angles of the first mounting plate 1 a and the second mounting plate 1 b to be within a preset range, so that a user can safely drive the man-machine interaction sport vehicle. It can be understood that the second end of the rotating rod 2 a can also be fixed, while the first end is rotatable.

Of course, in other embodiments, the rotating rod 2 a can be rotatably matched with both the first groove 1 a 3 and the second groove. Correspondingly, the rotating structure 2 further includes two second pressing blocks 2 d. The structures of the two ends of the rotating rod 2 a are similar to the structure of the second end of the rotating rod 2 a, the assembly relationship is the same as above, and the descriptions thereof are omitted herein.

In the present embodiment, referring to FIG. 6, the second end of the rotating rod 2 a is further configured with a sleeve 2 b. The second end of the rotating rod 2 a is rotatably connected with the second mounting plate 1 b through the sleeve 2 b in a matching manner and by cooperating with the second pressing block 2 d. The second end of the rotating rod 2 a rotates about the axis of the rotating rod 2 a through the sleeve 2 b. The sleeve 2 b is arranged to reduce the contact area between the second end of the rotating rod 2 a and the second groove, so as to facilitate the rotation of the second end of the rotating rod 2 a while avoiding the wear of the rotating rod 2 a to effectively protect the rotating rod 2 a.

Referring to FIG. 6, the sleeve 2 b is sleeved on the outer surface of the rotating rod 2 a close to the second end. The rotating rod 2 a can be divided into at least two sections, and a step structure is provided between the two sections. The first end of the sleeve 2 b abuts against the step structure, and the second end of the sleeve 2 b does not move left and right due to the presence of the first limiting portion 2 a 2 and the second limiting portion 2 d 1.

In other embodiments, the two ends of the rotating rod 2 a can be rotatably matched with both the first groove 1 a 3 and the second groove. It can be understood that when the two ends of the rotating rod 2 a can be rotatably matched with both the first groove 1 a 3 and the second groove, the rotating structure 2 further includes two second pressing blocks 2 d. The two second pressing blocks 2 d are fixedly mounted to the first mounting plate 1 a and the second mounting plate 1 b, respectively. One end of the rotating rod 2 a is disposed between the second pressing block 2 d and the first mounting plate 1 a while being rotatably connected with the two in a matching manner. The other end of the rotating rod 2 a is provided between the second pressing block 2 d and the second mounting plate 1 b while being rotatably connected with the two in a matching manner. Further, in the present embodiment, the two ends of the rotating rod 2 a are identical in structure and are identical in structure to the second end of the rotating rod 2 a in the above embodiment. Further, the sleeve 2 b can also be provided at the two ends of the rotating rod 2 a. In other embodiments, one end of the rotating rod 2 a can be fixed to the first mounting plate 1 a by welding or the like, and the other end is disposed between the second pressing block 2 d and the second mounting plate 1 b while being rotatably connected with the two in a matching manner.

The top surface 1 a 1 of the first mounting plate 1 a may be configured with a plurality of first reinforcing ribs 1 a 4. The first reinforcing ribs 1 a 4 are made of a same material as the first mounting plate 1 a, that is, the first reinforcing ribs 1 a 4 and the first mounting plate 1 a can be obtained by an integral molding process. The first mounting plate 1 a and the second mounting plate 1 b can be made of a metal-containing material such as iron, aluminum, copper, alloy, etc., so as to ensure that the first mounting plate 1 a and the second mounting plate 1 b act as a total mechanical bearing structure. The first mounting plate 1 a and the second mounting plate 1 b can serve as a skeleton of the human-machine interaction sport vehicle 10, and can directly bear the weight of the user. The first reinforcing ribs 1 a 4 can be convex strips or in other shapes as long as they can function to strengthen the mechanical properties. The overall shape of the first mounting plate 1 a is not limited, may be set according to specific needs, and may be rectangular, fish-like or the like. A thickness of the first mounting plate 1 a is not limited and may be determined according to specific needs and mechanical strength of the materials used. In the present embodiment, the overall shape of the first mounting plate 1 a is fish-like, the “fish body” may be a pedal area, and the “fishtail” may be used for mounting other elements.

Referring to FIGS. 1 and 2, the top cover 4 includes a second top cover (not shown) and a first top cover 4 a which are symmetrically arranged and rotatable relative to each other. The first top cover 4 a is disposed above the first mounting plate 1 a. That is, the first top cover 4 a is disposed on the top surface 1 a 1 of the first mounting plate 1 a. The second top cover is disposed on the top surface of the second mounting plate 1 b. The second top cover has the same structure as the first top cover 4 a. The first top cover 4 a is now used for explanation.

Referring to FIG. 1, a surface of the first top cover 4 a that is away from the bottom surface 1 a 2 of the first mounting plate 1 a is configured with a recessed portion 4 a 1 in a middle position thereof. The recessed portion 4 a 1 is configured with a pedal 4 a 2 and a foot pad 4 a 3 covering the pedal 4 a 2. The foot pad 4 a 3 is provided with a plurality of rubbing strips (not shown) for increasing friction.

The shape of the top cover can be designed according to specific needs. Since the top cover is not a total bearing structure, the top cover of different styles and shapes can be replaced according to the preference while the mounting plate is unchanged to meet the needs of users of different ages and individualities.

Further, the second top cover and the first top cover 4 a are each connected with an arc-shaped convex cover. Taking the first top cover 4 a as an example, the first top cover 4 a is connected with an arc-shaped convex cover 4 a 4. The first end of the arc-shaped convex cover 4 a 4 is engaged into the recessed portion 4 a 1, and the second end opposite to the first end is located above the first wheel 3 a and covers part of the first wheel 3 a. A contour of the first end of the arc-shaped convex cover 4 a 4 matches a contour of the recessed portion 4 a 1 so as to ensure that the two can be engaged with each other in a matching manner.

Further, positions where the second top cover and the first top cover 4 a are close to each other are each configured with a prompt plate 4 a 5. The prompt plates 4 a 5 are connected with the balance control system, one of the prompt plates 4 a 5 is a prompt plate for displaying power capacity, the other one is a prompt plate for displaying whether the sport vehicle works, and each prompt plate 4 a 5 has a transparent cover.

Referring to FIG. 3, a surface of the first top cover 4 a that is close to the bottom surface 1 a 2 of the first mounting plate 1 a is configured with a plurality of second reinforcing ribs 4 a 6 and a plurality of fixed pillars 4 a 7. The overall distribution of the second reinforcing ribs 4 a 6 may be rectangular lattices or honeycomb lattices. The second reinforcing ribs 4 a 6 are plates or pillars raised outward from the surface of the first mounting plate 1 a. The material for the second reinforcing ribs 4 a 6 is not limited, and may be the same material as for the first mounting plate 1 a, or may be a different material. The second reinforcing ribs 4 a 6 are arranged to improve the mechanical strength of the first top cover 4 a. A surface of the second top cover that is close to the mounting plate is also configured with a plurality of first reinforcing ribs and a plurality of fixed pillars, and the descriptions thereof are omitted herein. When the user is located on the top cover, since the top cover (i.e., the second top cover and the first top cover 4 a) is provided with reinforcing ribs, it has good mechanical strength and is more capable of bearing the weight of the user. Compared with the solution for achieving better mechanical strength by increasing a thickness of the top cover, the top cover provided with the reinforcing ribs not only has good mechanical strength, but also has light overall weight, which is beneficial to reducing the overall load of the human-machine interaction sport vehicle 10.

The top cover and the bottom cover may be made of plastic, which facilitates spraying, coloring and other process on the appearance of the vehicle body and achieves anti-fouling and water-proofing effects while reducing the weight of the entire body. The bottom cover includes a second bottom cover (not shown) and a first bottom cover 5 a which are symmetrically arranged and rotatable relative to each other. The second bottom cover has the same structure as the first bottom cover 5 a.

Taking the first bottom cover 5 a as an example, the first bottom cover 5 a is disposed below the first mounting plate 1 a. The first mounting plate 1 a is located between and matched with the first top cover 4 a and the first bottom cover 5 a. That is, the first top cover 4 a is matched with the first bottom cover 5 a to clamp the first mounting plate 1 a therebetween. The first top cover 4 a and the first bottom cover 5 a can be fixed together by a buckle, a screw, a chute or the like. In the present embodiment, the first bottom cover 5 is disposed on the bottom surface 1 a 2 of the first mounting plate 1 a.

In the present embodiment, a surface of the first top cover 4 a that is close to the top surface 1 a 1 of the first mounting plate 1 a is further configured with a plurality of fixed pillars 4 a 7, and the fixed pillars 4 a 7 are hollow pillars. The cross sections of the pillars may be circular, rectangular, rhombic, etc. The plurality of fixed pillars 4 a 7 may be divided into a first group of fixed pillars, a second group of fixed pillars and a third group of fixed pillars. The first group of fixed pillars is configured to assemble with the bottom cover, the second group of fixed pillars is used for assembling a circuit board 7 of the balance control system, and the third group of fixed pillars is used for assembling the corresponding mounting plate.

The two wheels may be specifically defined as a first wheel 3 a and a second wheel 3 b. The first wheel 3 a is connected with the first mounting plate 1 a. The first wheel 3 a and the second wheel 3 b are opposite. The first wheel 3 a and the second wheel 3 b are interchangeable when the human-machine interaction sport vehicle 10 rotates 180 degrees. The first wheel 3 a has the same structure as the second wheel 3 b. The first wheel 3 a may include a wheel body and a tire. The hub motor can be mounted to the mounting plate or respectively disposed in the two wheels. In the present embodiment, the hub motor is hermetically fixed in the wheel body, so that a larger-sized hub motor can be used to achieve obvious advantages in motion stroke and speed over a human-machine interaction sport vehicle having a motor mounted at the bottom of the bottom cover. The tire surrounds the wheel body. Referring to FIG. 6, taking the first wheel 3 a as an example, the first wheel 3 a may further include a fixed axle 3 a 1. The fixed axle 3 a 1 extends out from a center position of the first wheel 3 a and is fixed to the first mounting plate 1 a. The first wheel 3 a can be fixed to the first mounting plate 1 a by coordination of a fixed pressing block 3 a 2 and the fixed axle 3 a 1. It can be understood that the first wheel 3 a is fixed to the first mounting plate 1 a by not only such method but also other methods, as long as the first wheel 3 a is fixed to the first mounting plate 1 a.

In the present embodiment, the second reinforcing ribs 4 a 6 and the plurality of fixed pillars 4 a 7 are made of a same material as the top cover. The second reinforcing ribs 4 a 6, the plurality of fixed pillars 4 a 7 and the first top cover 4 a are integrally formed.

The balance control system is disposed in the vehicle body. The balance control system includes a power supply 6 and the circuit board 7. A controller and a plurality of sensors are configured on the circuit board 7 to control running states of the first wheel 3 a and the second wheel 3 b. Specifically, the circuit board 7 is disposed between the top cover and the bottom cover and fixed on the top cover. More specifically, the circuit board 7 is fixed to the top cover by the fixed pillars 4 a 7. The power supply 6 is disposed between the mounting plate and the bottom cover. The number of the circuit board 7 may be one, or two, that is, a circuit board 7 is disposed on each of the first top cover 4 a and the second top cover. It can be understood that the two circuit boards 7 can share one power supply 6. In the present embodiment, a circuit board 7 is disposed on each of the first top cover 4 a and the second top cover.

Specifically, referring to FIG. 3, the circuit board 7 is mounted on the fixed pillars 4 a 7 of the first top cover 4 a. An accommodating space is formed between the circuit board 7 and the first top cover 4 a. At this moment, the first mounting plate 1 a is engaged onto the first top cover 4 a and partially disposed between the first top cover 4 a and the circuit board 7. One side of the circuit board 7 is connected with a heat dissipating component 8. The heat dissipating component 8 is perpendicular to the surface of the circuit board 7. The accommodating space is used for accommodating the heat dissipating component 8 to well protect the heat dissipating component 8. At the same time, the space can be fully utilized by such a way that the heat dissipating component 8 is perpendicular to the circuit board 7, so that the overall size is relatively small. Compared with the conventional method of directly bonding the heat dissipating component to the circuit board, the heat dissipating component 8 is perpendicular to the circuit board 7 so that the airflow space at two sides thereof can be used for sufficiently dissipating heat, and the heat dissipation efficiency is high. The heat dissipating component 8 can be fixed to the circuit board 7 by soldering or the like. It can be understood that a plurality of electronic components that dissipate much heat, such as power tubes (unmarked), may also be disposed on the side, close to the circuit board 7, of the heat dissipating component 8. The heat dissipating component 8 may be made of iron, aluminum, copper, alloy, etc. Of course, the structure and principle adopted for disposing the circuit board on the fixed pillars of the second top cover are the same as the above, and the descriptions thereof are omitted herein.

The controller is electrically connected with the plurality of sensors, the power supply 6 and the hub motor. The controller controls the hub motor according to the sensing signals transmitted by the sensors to drive the wheels to rotate. Specifically, the sensors include a gyroscope, an acceleration sensor and an inductive switch. The inductive switch is used for sensing whether the user is standing on the human-machine interaction sport vehicle to turn on or off. The controller receives a sensing signal of the inductive switch to control whether the hub motor works. The controller receives the sensing signals of the acceleration sensor and the gyroscope to control whether the hub motor changes the state. Specifically, the plane where the two pedals are located tilts forward, tilts backward or is parallel to the horizontal plane by controlling the center of gravity of the user, so that the human-machine interaction sport vehicle accelerates forward, decelerates and moves backward, or runs at a constant speed, that is, achieving “human-machine interaction”.

Further, the mounting plate is further configured with a tail lamp 1 c, and the tail lamp 1 c is connected with the balance control system. The tail lamp 1 c is powered by the balance control system and controlled by it to turn on or off. The tail lamp 1 c is configured to light up during deceleration. A transparent tail lamp cover (not shown) is configured outside the tail lamp 1 c.
